NiTEn STATES PATENT WINDOW SASH AND FRAME..

SPECIFICATION forming part of Letters Patent No. 383,134, dated lvliay22, 1888.

Application filed December 20, 1886. Serial No. 222130.

To all whom, it may concern.-

Be it known that I, CONRAD KRUEsI, a citizen of Switzerland, residing atChicago,in the county of Cook and State of Illinois, have invented acertain new and useful Improvement in W'indow Sash and Frames,of whichthe following is a specification, to wit:

This invention relates to an improvement in window sash and frames; andit consists in certain novel details of the construction and arrangementof the same, whereby the sash is more readily removed and replaced andis locked and heldat any place, substantially as Will be hereinaftermore fully set forth and claimed. y

In order to enable others skilled in the art to which my inventionpertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the accompanying drawings, inwhich- Figurel is a front elevation of a window frame and sash fitted asI shall describe. Fig. 2 is a central vertical section of the same; Fig.3, a horizontal section of the same. Fig. 4 is an enlarged detail crosssection of a part of one ofthe sash-rails and my fastenerand guide. Fig.5 is a detail front elevation of the guide partly brokenaway. Figs. 6and 7 are views similar to Figs. 4 and 5, but representing the device ina different position. Fig. 8 is a plan view, and Fig. 9 an edge View, ofthe casting in which the guide is hinged. Fig. 10 is atop view, and Fig.1l a side view,of my device for securing the sashcord.

A represents a window-frame of any suitable size and shape, and eitherwith or without the usual weightwell, according as it is desired to usea balanced sash or not. This frame is on its inner sides provided withtwo shallow vertical grooves, b,instead of the usual dividing and guidestrips; and while the form of these grooves may be greatly varied tosuit dil-'ferent circumstances, I prefer the shallow halfround formshown in the drawings. These grooves being sunk in the frame leaves theentire face of the frame smooth and free for the insertion and removalof the sash, as will be presently explained.

The upper and lower sash, B C, are made, in the usual manner,of a sizeto tit the frame.

(No model.)

are forced into these grooves by means of small eccentric levers ef,pivoted upon studs g It' on the side rails of the sash. The eccen` triclevers work against wings p on the leaves a c, which project forward andare turned over the front of the sash. As seen in Figs. 5 and 7, theselevers are eccentrically pivoted, leaving upon one side of the pivotsasmall part, ef, and upon the other a larger portion, c fi, and it willbe evident that when these levers are turned to press their larger sidesagainst the hinged guides these latter are forced into the framegroovcswith varying force, either to serve as a guide for the sash in beingraised or lowered or so tightly as to iirmly lock the sash andeft'ectually prevent its being moved. Vith this device to hold the sashthe window can be perfectly secured at 'any point without the aid ofbalance weights; but I prefer to use such weights,and secure theirsupporting-cord H, knotted at its end,in a small metallic socket, F.,which is provided with a screw, Cr, to secure it to the sash, and has inone side an angular slot, 7i, opening through the outer edge of thesocket, as will be understood from Figs. l0 and 11. The cord is readilyinserted and removed from the angular slot, and is securely held inplace when the sash is in the frame.

The operation of this device is at once plain. The sash, when placed inthe frame, is guided in lifting and lowering by the hinged leaves orguides a c, which run in the grooves b d in the frame and retain thesash in place exactly as is done by the stops and beads in common use.Vhen the sash is to be locked in any position, either closed orpartially or wholly open, the eccentric levers are simply turned topress the hinged guide leaves more firmly into the IOO grooved frame,and thus firmly secure the sash perfectly immovable. When the sash is tobe taken out for cleaning or repairs, it is only necessary to turn theeccentric levers in the opposite direction, and the guide-leaves can beswung out on their hinges and leave the sash free to be drawn out of theframe and returned again without the use of tools of any kind. Theconvenience of this will be seen at a glance, and also that the hingedleaves are readily adjusted for shrinkage or swelling ofthe sash, causedby variations of Weather, and take up all looseness and rattling.

The particular form of the hinged .guideleaves and their size will ofcourse be regulated according to the dictates of fancy or therequirements of particular cases, and may be made of fancy form andornamented according to taste or desired economy of construction.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination, with a Window-frame formed with grooved sides, ofasash provided with guides pivoted to the sash and provided With'tongues to t into the grooves, and projecting wings projecting in frontof the sash,

'and means, substantially as described, for operating said guides.

2. The combination, With a Window-frame formed with vertically-groovedsides, of a sash having its edges recessed, guides or leaves hinged insaid recesses and projecting beyond the face of the sash, and eccentriclevers pivoted upon the sash-rail and bearing against the projectinghinged leaf to press it into the groove with the required force,substantially as shown and described.

In testimony whereof I afx mysignature in the presence of two Witnesses.

CONRAD KRUESI.
